Table 5. Commands
Note: X Don’t Care, PA Program Address, PD Program Data, BA Any address in the Block.
All values in the table are in hexadecimal.
The Command Interface only uses address bits A0-A10 to verify the commands, the upper address bits are Don’t Care.
Read/Reset.
After a Read/Reset command, read the memory as normal until another command is issued.
Auto Select.
After an Auto Select command, read Manufacturer ID, Device ID or Block Protection Status.
Program, Unlock Bypass Program, Chip Erase, Block Erase.
After these commands read the Status Register until the Program/Erase
Controller completes and the memory returns to Read Mode. Add additional Blocks during Block Erase Command with additional Bus Write
Operations until the Timeout Bit is set.
Unlock Bypass.
After the Unlock Bypass command issue Unlock Bypass Program or Unlock Bypass Reset commands.
Unlock Bypass Reset.
After the Unlock Bypass Reset command read the memory as normal until another command is issued.
Erase Suspend.
After the Erase Suspend command read non-erasing memory blocks as normal, issue AutoSelect and Program commands
on non-erasing blocks as normal.
Erase Resume.
After the Erase Resume command the suspended Erase operation resumes, read the Status Register until the Program/
Erase Controller completes and the memory returns to Read Mode.

Unlock Bypass Command.
The Unlock Bypass
command is used in conjunction with the Unlock
Bypass Program command to program the memo-
ry. When the access time to the device is long (as
with some EPROM programmers) considerable
time saving can be made by using these com-
mands. Three Bus Write operations are required
to issue the Unlock Bypass command.
Once the Unlock Bypass command has been is-
sued the memory will only accept the Unlock By-
pass Program command and the Unlock Bypass
Reset command. The memory can be readas if in
Read mode.
Unlock Bypass Program Command.
The Unlock
Bypass Program command can be used to pro-
gram one address in memory at a time. The com-
mand requires two Bus Write operations, the final
write operation latches the address and datain the
internal state machine and starts the Program/
Erase Controller.
The Program operation using the Unlock Bypass
Program command behaves identically to the Pro-
gram operation using the Program command. A
protected block cannot be programmed; the oper-
ation cannot be aborted and theStatus Register is
read. Errors must be reset using the Read/Reset
command, which leaves the device in Unlock By-
pass Mode. See the Program command for details
on the behavior.
Unlock Bypass Reset Command.
The
Bypass Reset command can be used to return to
Read/Reset mode from Unlock Bypass Mode.
TwoBus Write operationsare required toissue the
Unlock Bypass Reset command.
